About NATE

What or Who is NATE?

North American Technician Excellence (NATE,) headquartered in Arlington, VA., was founded in 1997 and is the nation’s largest non-profit certification organization for heating, ventilation, air conditioning and refrigeration technicians. NATE is the only technician certification organization governed, owned, operated, developed and supported by the HVACR industry.
NATE's certification tests represent real world working knowledge of HVAC and HVACR systems and candidates can earn installation and/or service certification in one or more specialty areas. NATE certification tests are developed by the NATE technical committee. The NATE technical committee is comprised of industry experts who developed and oversee NATE’s Knowledge Areas of Technician Expertise (KATEs). Each exam is developed based on these knowledge areas of expertise. The technical committee represents a wide variety of perspectives including contractors, educators, manufacturers, and utilities. Members also are diversely spread throughout the country.

How are RSES and NATE Affiliated?

RSES supports having a single examination/credentialing body to measure technical competency within the HVACR industry - as such, RSES is one of the many industry organizations that endorses and promotes NATE certification within the HVACR industry.
RSES and NATE have a unique relationship in that NATE does not provide any training or preparation materials for their examinations – although they do strongly recommend that technicians prepare! RSES, as a training orginazation, offers several programs to help technicians prepare to get NATE certified and maintain that certification.

Where can I get training and/or take the exam?
